Abstract: | Tetra-azidodiamminecobaltates(III): cis-Co(N3)4(NH3)2]? and Co(N3)4en]? The preparation and the properties of complexes containing the anions cis-Co(N3)4(NH3)2]? and Co(N3)4en]? are described. The compounds Co(NH3)6]Co(N3)4(NH3)2 · H2O], Co(N3)2(NH3)4]Co(N3)4(NH3)2], As(C6H5)4]Co(N3)4en], cis- and trans-Co(N3)2en2]Co(N3)4en] have been isolated. |
